Ultimate Tanking Spec?

Alright I've been playing for awhile now mostly into the financial aspect of the game. Selling/Trading but I am level 14 with 7 points to spend in skills and I want to level up to start tanking and runing levels. I put my first 6 into increase mass. When I finally open up all the skills which ones must as a tank be increased and to what amount? I'm not looking to pvp till later in the game. For now I just want a solid tank build. I have also solely increased strength.
